The best I found is a audiobook series called “The hitman’s guide” but if you mean on this site the best choice is “Heavenly Soul” by crimson_carnation.
Shameless self-promo: My story DragonBound (link in bio) has a genuine plot, and scenes between girl/girl, guy/guy, futa/girl, and boy/girl. Anything outside of futa/girl and boy/girl is marked, and all NSFW chapters are labeled as such.
